[@Kyoka]: Ah... See, er, this is in continuity with the original FSN version of the Nasuverse(up until the third War), meaning that Arturia can [i]only[/i] be summoned in her more mature, Excalibur-wielding incarnation.

[@Avalon]: Emiya would be pretty interesting, honestly. The Reality Marble rule(and the NP count rule) are admittedly mostly in place to discourage people from overloading OC Servants on abilities. I want people to ask first and check with [@PKMNB0Y], [@Raineh Daze], and myself if they want to do anything like that.
